Over the past few days now, I've been testing out Tresorit's secure cloud storage and file sharing app on my Mac and BlackBerry Z30. It's essentially a Dropbox competitor but aims to be more secure, along the lines of SpiderOak. The app has now arrived in BlackBerry World and is available to all who wish to sign up for an account.
As with all storage services these days, you get free storage on the free tier starting with 5GB, which can grow with referrals. If that's not enough for you, the Pro accounts start at $7.99 for 20GB and go all the way up to 1000GB for $129.99.
- Not all cloud solutions are created equal. - Dropbox, Box and others only encrypt your data during transferring, but they decrypt it on their servers in the cloud. That way, they have access to your confidential files and can see what's inside them.
- Tresorit keeps your data encrypted in the cloud.- Your confidential files are encrypted using the most advanced encryption methods. No one, not even Tresorit administrators, hold your decryption key. A single file can only be accessed by you and those whom you shared it with.
- Send encrypted files - Share end-to-end encrypted folders to provide secure and automatic access. Use encrypted links to send files securely to friends, colleagues and clients.
- Control - Protect your files by setting easy to manage access levels – manager, editor, reader. Track revisions, devices, and user activity. Change or revoke privileges at any time.
- Compliance by design - As Tresorit never gets data in unencrypted form and it's designed to address modern day security threats, Tresorit technology and data centers provides you the level of trust required of ever more rigorous compliance standards.
I can't speak on the validity of their claims about being more secure vs. the other options out there, but they initiated a bounty of $50,000 and invited leading Universities and hackers to breach the service. No one has succeeded despite attempts by over 900 'hackers' over the course of 498 days including those from MIT, Stanford, Caltech, and Harvard. I'm never one to turn down free storage, so while I may never share truly personal info there, I'll gladly make use of the 5GB of space.
